I don't have either of those, but does your version of "Funkytown" appear on the flip side of "The Chase," or is it a standalone release?
Here's some more 12-inchers I have from that disco period:

I highly recommend you get "Amant"!!
If you don't have Cerrone "Supernature" album, I highly recommend that one too!!
Yes, the "Funkytown" is the original 12" single, also have the album too.
I do have the "Ain't No Stopping Us Now" album. Also have an Evelyn Thomas album from the late '70's on Casablanca, which is a bit on the rare side.
